IMPROVEMENT la! STEAM-CONSENSERS.

Specification forming part of Letters Patent No. l, dated March 17,1874; application filed November 13, 1873. Y

To all whom t may concern:

Be it known that I, THoMAs L. JONES, of Natchez, Mississippi, haveinvented new and useful Improvements in Steam Condensers, of which thefollowing is a full, clear, and eX- act description, reference being hadto the accompanying drawing making a part of this specification, and tothe letters of reference thereon marked, in which- Figure l is a centralsectional elevation. Fig. 2 is a cross-section looking upward to theperforated crown-sheet. The cover above is removed to show the jet. Fig.3 is a crosssection looking` downward to the bottom of the condenser.

Like letters 'of like kind indicate like parts.

The object of the present invention is to provide a condenser that issimple in construction and operation, compact, accessible; that isoperative at a point several feet above the level of the water-supplyused in condensing; and that readily brings the steam in contact withthe cooling agent.

In the accompanying drawing, A represents a condensing-chamber. In itsgeneral form it. is cylindrical, and is ar 1anged vertically. Brepresents an inlet water-pipe extending from the water-source belowupward through the chamber A at the center thereof', and through the topO of the chamber, which is made convex, as shown in figure. The top O,as well as the side wall D of the chamber, is perforated. E represents atight cover, also, preferably, convex, that fits closely down onto theupper end of the side of the chamber A, but leaving a space, F, abovethe perforated top O. A casing, G, incloses the chamber A and cover E,extending down the side of the chamber as far as the perforationstherein, and, if preferred, to the bottom M of the chamber. A space,however, is left above the cover E, and an annular space around theIwall l). From the center of the casing above a neck, H, extends upward,connecting with the pipe leading to the engine. I represents what I terman auxiliary sgray, consisting of a tube, J, leading down from awater-tank above, (not shown,) and an upturned jet, K, arranged in theneck H. L L represent discharge waterpipes, through which the water inthe condenser is drawn down and oft' into a hot-well by means ofsuitable pumps.

The operation of the above-described invention is as follows: Steambeing turned down through the neck II, it encounters a spray from thejet K. This spray is used only in starting a vacuum. Once started, thevacuum is maintained by the condensation of the. steam in the chamber A.Owing to the vacuum the water rises` in the inlet-pipe B, and Hows overthe perforated crown-sheet C. By reason of the conveXity of the top C,the water not only spreads freely over it, but tends to collect at itscircumference. Falling through the top of the chamber, it descends in aheavy shower therein. At the same time the steam, passing over the coverE and down into the annular space around the side of the chamber andthrough the perforations therein, is rapidly condensed. Owing to theplentiful supply of cool water, and its descending freely through thecondensing-chamber, and the introduction of the steam all around thechamber, it is found practicable (this condenser having been insuccessful use for a considerable time on the steamer Natchez, on thelower Mississippi) to condense a very large quantity of steam in a verycompact apparatus. Moreover, as the condenser supplies itself withwater, it can be located above the water-line, and in an accessibleposition, and in a place where its heat will not be prejudicial to thecargo, as is the case frequently when a condenser is located iu the holdof the steamer. Further, as the condenser can be placed on deck, theouter casing, being chilled by the surrounding atmosphere, operates asan additional cooling surface.

Having described my invention, what I claim as new therein is Thehereinbefbre-described condenser, consisting of the chamber A, providedwith the inlet-pipe B, crown-sheet C, side wall I), and cover E, anddischarge-pipes L L', the casing Gr, provided with the neck H, and theauxiliary spray I, all arranged and operating slibstantially asdescribed and shown.
